Re: Starting whole milk! What do you do?
TBH, my kids never cared one way or the other whether it was milk or formula in their bottles so we didn't too too much in the way of transition.
Pasteurized milk really doesn't go bad that quickly so other than in the summer I didn't worry too much about taking milk out and about. Generally I did like pp's and used milk at home and water when out. Or I would freeze the bottle of milk if we were going to be out a lot.
